DITCHING PLOW.

Patented Feb. 5, 1907.

Application filed May 21, 19706. Serial No. 317,942.

To all whom it muy concern:

Be it known that I, WILLIAM MAULTBY BENSON, a citizen of the United States, and a resident of Newport, in the county of Perry and State of Pennsylvania, have inventeda new and Improved Grooving and Ditching Plow, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a tandem gang grooving-plow, articularly adapted for use in semi-arid lan and to`so construct the implement that the plows are set tandem or one directly behind the other, each consecutive plow-pointl being set deeper in the furrow than the preceding one for the purpose of producing a dee groove at one operation, and wherein also t e plowpointsare of graduated width, the lowest be- 1ng the narrowest andthe uppermost one the widest. Thus each point has a comparatively small amount of ground to plow up, and the side walls of the grooves are not torn up and loosened as they would be 1f but a single plow were used to make a deep cut at one operation, and also comparatively httle power is needed to draw the plow when constructed as above.

The invention consists in thenovel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improved plow. Fig. 2 is a bottom plan view of the plow, and Fig. 3 is a transverse vertical section thereof.

The body A of the plow is preferably of skeleton construction, and, as illustrated, it

consists of upper and lower parallel side beams 10 and 11 of angle-iron, vertical side beams 12, and any desired number of transverse connecting-beams, together with crossbraces 13, as is best shown in Fig. 1. The body A is provided with a rear axle 14, having suitable supporting-wheels 15 mounted thereon, and a forward pivoted axle 16, also provided with proper supporting-wheels 16n and with a draft tongue or pole 17.

Adjacent to the forward and the rear axle, about midway between the sides of the body A, guide columns B are perpendicularly placed, extending above and below the said lbody, as is shown best in Fig. 1. These guide-columns B are open at their inner sides or the sides which face one another, as is shown in Fig. 2, andthe columns at their lower portions are usually held in place by angle-irons 18, securedehto the columns and to suitable bars 19, carried by lthe axles.

At the top of the body A these guide-columns B are passed between transverse beams 20, usually made of channel-iron, and opposing beams 20 are connected by a thrust-plate 21. Each thrust-plate 21, as is shown in Fig. 3, is provided with a central plain opening 22a, also centrally located with respect to the upper ends of the columns B, and a screw 22 is passed through each of the openings 22 into and through each guide-column B, as is also shown in 141g. 3. i Each screw 22 is provided with uppercollars 23 and 24, located one above and the other below the thrust-plate 21., through which the screw passes, and each screw is likewise provided at its upper end with a hand-wheel 25, the handwheels of the two screwsbeing connected by a belt 26, so that upon operating one screw the other will be simultaneously operated.

The ends of the beam O are recelved in the columns B, and the said beam C is preferably in the form of an inverted U or is a channeliron, as is shown particularly in Fig. 3. Adjacent to each end of the beam C interiorlythreaded sleeves 27 are provided, which receive the threaded portions of the screw-- shafts 22, so that by turning the shafts 22 the beam C is raised or lowered, as may be required, and each screw-shaft 22 is provided with a collar 28 at its lower end below the lower face of the beam C. This beam carries a number of plow-Shanks. The Shanks are arranged one 1n advance of the other or one immediately behind the other and are secured in any desired manner at their upper ends to the bottom of the beam C, asis shown in Figs. 1 and 2, and the said Shanks are given. a downward and forward inclination, as is best shown in Fig. 1. Each shank is provided with a point at its lower end of any suitable formation, and any desired number of Shanks may be employed.

In the drawings five Shanks are shown, commencing at the rear the Shanks being designated as D, D', D2, D3, and D4, and their points are designated d, d', d2, d3, and d4. The Shanks are graduated in length, the point of the rearmost shank entering the ground to the greatest depth, while the point ICO IIO
